Chandra Observations of Candidate Sub-Parsec Binary Supermassive Black Holes

M. Lynne Saade, Daniel Stern, Murray Brightman +10

We present analysis of Chandra X-ray observations of seven quasars that were identified as candidate sub-parsec binary supermassive black hole (SMBH) systems in the Catalina Real-T…

Circumbinary Disks: Accretion and Torque as a Function of Mass Ratio and Disk Viscosity

Paul C. Duffell, Daniel D'Orazio, Andrea Derdzinski +4

Using numerical hydrodynamics calculations and a novel method for densely sampling parameter space, we measure the accretion and torque on a binary system from a circumbinary disk.…

LISA and the Existence of a Fast-Merging Double Neutron Star Formation Channel

Jeff J. Andrews, Katelyn Breivik, Chris Pankow +2

Using a Milky Way double neutron star (DNS) merger rate of 210 Myr, as derived by the Laser Interferometer Gravitational-Wave Observatory (LIGO), we demonstrate that the Las…

Spikey: Self-Lensing Flares from Eccentric SMBH Binaries

Betty X. Hu, Daniel J. D'Orazio, Zoltan Haiman +4

We examine the light curves of two quasars, motivated by recent suggestions that a supermassive black hole binary (SMBHB) can exhibit sharp lensing spikes. We model the variability…

Repeated Gravitational Lensing of Gravitational Waves in Hierarchical Black Hole Triples

Daniel J. D'Orazio, Abraham Loeb

We consider binary black holes (BBHs) in a hierarchical triple system where a more compact, less-massive binary is emitting detectable gravitational waves (GWs), and the tertiary i…

Probing the Survival of Planetary Systems in Globular Clusters with Tidal Disruption Events

Kyle Kremer, Daniel J. D'Orazio, Johan Samsing +2

Among the growing list of confirmed exoplanets, the number of planets identified in dense star clusters remains sparse. Previous analyses have suggested this may be due in part to…
